Running Node removal from baseline

The documentation describes the use case where a node is stopped and removed from the baseline, which reduces the number of backups/replicas when the node is stopped. I assume that there is no current code to support removing the node from the baseline first, so that at least desired number of bac

RE: Deadlock during cache loading

In our case we're only using the receiver as you describe, to update the key that it was invoked for. Our actual use case is that the incoming stream of data sometimes sends us old data, which we want to discard rather than cache. So the StreamReceiver examines the value already in the cache and ei

RE: Deadlock during cache loading

Well, that’s diving a bit deeper than the “don’t do cache operations” rule of thumb, but let’s do that. When receiver is invoked for key K, it’s holding the lock for K. It is safe to do invoke on that K (especially if you control the invoked code) since it is locked already. But it is not safe t

RE: High cpu on ignite server nodes

Hi Stan, Thanks for your analysis. We have increased the on heap cache size 50 and added expiry policy [30mins]. The expiry policy is expiring the entries and the cache is never reaching to it's max size. But now we see high heap usage because of that GCs are happening frequently and FULL GC

RE: Deadlock during cache loading

Hi Stan, Thanks for taking a look. I'm having trouble finding anywhere that it's documented what I can or can't call inside a receiver. Is it just put()/get() that are allowed? Also, I noticed that the default StreamTransformer implementation calls invoke() from within a receiver. So is that

Are you enabling the extra flags required for the JVM work detect memory and work properly? Specifically adding the following options to the JVM options when starting ignite -XX:+UseCGroupMemoryLimitForHeap. The -XX:+UnlockExperimentalVMOptions See: https://blogs.oracle.com/java-platform-grou

Hi, Could you please provide your configuration files? How many nodes did you start in your container? BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: And again... Failed to get page IO instance (page content is corrupted)

Hi, We've found and fixed few issues related to ExpiryPolicy usage. Most likely, your issue is [1] and it is planned to ignite 2.6 release. [1] https://issues.apache.org/jira/browse/IGNITE-8659 On Fri, Jun 22, 2018 at 8:43 AM Olexandr K wrote: > Hi Team, > > Issue is still there in 2.5.0 > >

Re: setting baseline topology in kubernetes

Hi, No 11211 is a default ignite TCP port. For every new node, it will be incremented 11211, 11212, 11213, etc. Also please check that you didn't overwrite it. https://www.gridgain.com/sdk/pe/latest/javadoc/org/apache/ignite/spi/discovery/tcp/TcpDiscoverySpi.html#setLocalPort-int- And yes igni

Hi, At least one backup, got it. Thank you. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: setting baseline topology in kubernetes

Hi Alex, It accepts an IP and port as an argument. Do I need to enable ignite rest and expose rest endpoints on cluster nodes for this to work? Thanks, Arun -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
